AIRr'TIG'HT RECEPTACLE.

Specification of Letters Patent.

Patented Aug. 18, 1914.

- Application filed September 21, 1911. Serial No. 650,611.

' citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,'have invented certain new and use ful Improvements in Air-Tight Receptacles, of which the following is a specification.

This invention relates to receptacles adapted to be used for marketing various articles or substanccswhich are'required to be kept hermetically sealed until such time as. they are to be used.

One of the objects. of the invention is the.

provision of a receptacle of this character which shall be simple in construction, inexpensive to manufacture and which can be readily and quickly sealed after the contents have beenplaced therein and can be unsealed and opened without the employment of any tool or implement when the contentsare to be used.

. 'One form of my invention is shown in the drawings forminga part of this specification and from these drawings, when con-' sldered in connection with the following de-' scription, the invention will be understood and many of its advantages will be appreciated' I Referring to the drawingsFigure 1 is a perspective view of a receptacle embodyin my. invention and shown as closed an sealed. Fig. 2 is a similar View showing a the receptacle in open-position. Fig. 3 is a 5 is'a similar view of the detail perspective view of the sealingstrips. Fig. 4 is a transverse sectional view of the closed receptacle shown in Fig. 1; and Fig. receptacle after it has been unsealed.

From the drawings it will be observed that the receptacle comprises in general a body having end walls 5, a front wall 6 and a rear wall 7 of which the cover 8 forms an extension. The cover is provided at its free edge with a flap 9 and the end walls of the ody 5 are provided with flaps 10 adapted to be inturned beneath the cover of the box into the position shown in dotted lines in Fig. 1. The body of the receptacle and the cover therefor are preferably formed from a single sheet ofsuitable material such as heavy paper or caidboard, for instance, the receptacle being formed by cuttin a blank of suitable shape from the sheet 0 material and folding the blank to produce the box as shown in Fig-'2. The .box is held together by tabs or flaps which project inwardly from the front and rear walls 6 and 7 and are pasted or otherwise secured to the inner face of the end walls 5. The flaps indicated by reference character 11 in Fig. 2 are so shaped that thoir free edges abut on a median line of the end ,walls 5, but it will be body of the receptacle. One continuous strip of material can be folded so as to extend around the perimeter of the free edges of the box, if desired, but in the present instance, I have shown in Fig. 3 a plurality of strips of which the end strips 12 are the same length as the ends 5 of the box and the front strip 13 is the same length as the front wall 6 of the box. These strips are folded lengthwise one or more times, ifdesired, and are positioned upon a cord or string 14 as shown. After the rece tacle is filled and the cover is closed the top and outer faces of the strips are coated with any suitable adhesive and the strips are then inserted between the cover and the body of the receptacle. Theend strips 12 lie between the lower face of the cover and the upper face of the flaps 10 and the strip 13 lies be tween the outer face of the flap 9 and the inner face of the-front wall 6 as shown in Fig. 1. The adhesive secures one face of each strip to the cover and the other face to the body of the box throughout its length, thereby effectually sealing the box and resulting in an air-tight receptacle. The position .of the various parts when the box is sealed is shown in Figs. 1 and 4:.

W'hen it is desired to open the box the protruding end of the cord 14 may be grasped and pulled preferably in a direction at right angles to the face of the wall from which the cord protrudes. This action will tear the strips along the line of their folds thereby unsealing the receptacle so that it may be opened by lifting the'cover. I have shown on the drawings both ends of the cord 14 as protruding, but it will be obvious that one protruding end is sufficient and that gripping this free end and pulling the same the strips. will be severed and the receptacle unsealed.

Various changes in the size, shape, proportion and configuration of the various.

parts shown and described will suggest themselves to those familiar with the art,

air-tight receptacle, comprising a a cover therefor,a strip of material folded upon itself and interposed between the free edges of the cover and the corresponding free edges of the body and glued both to the body and thecover, and a cord 'ositioned in the fold of said strip with one end protruding outside the receptacle whereanon-me by said strip may be torn alongits fold to unseal the receptacle. I H

3. M air-tight receptacle, comprising a body, a cover, a plurality ofstrips, of folded material, each strip being connected with the cover and the body adjacent the free edges, and a cord arranged inthe folds of said strips around the perimeter-0f the-aeceptacle vwith one end protruding oliltside the receptacle to be grippedand pulled thereby tearing said strips along their folds to unseal thev receptacle.

4. An air-tight receptacle comprising a body, a covertherefor tacle when the cover is closed, a-strip of m terial folded upon. itself and interposed between the said flap and the body of the re.- ceptacle and glued to said body and flap to seal the receptacle, and a cord positioned in a fold of the said strip witli one end protruding' outside the receptacle said strip may be torn along its fold to unseal the receptacle.
